Title: modeswitches
| Old | New | Line | |
|---|---|---|---|
| 1 | + | Mode switches enable specific functionality and are enabled using the compiler directive {\$modeswitch name}. | |
| 2 | + | ||

| 10 | + | ` m_nested_comment, { nested comments }`\ | |
| 11 | + | ` m_tp_procvar, { tp style procvars (no @ needed) }`\ | |
| 12 | + | ` m_mac_procvar, { macpas style procvars }`\ | |
| 13 | + | ` m_repeat_forward, { repeating forward declarations is needed }`\ | |
| 14 | + | ` m_pointer_2_procedure, { allows the assignement of pointers to`\ | |

| 20 | + | ` m_default_para, { support default parameters }`\ | |
| 21 | + | ` m_hintdirective, { support hint directives }`\ | |
| 22 | + | ` m_duplicate_names, { allow locals/paras to have duplicate names of globals }`\ | |
| 23 | + | ` m_property, { allow properties }`\ | |
| 24 | + | ` m_default_inline, { allow inline proc directive }`\ | |
| 25 | + | ` m_except, { allow exception-related keywords }`\ | |
| 26 | + | ` m_objectivec1, { support interfacing with Objective-C (1.0) }`\ | |
| 27 | + | ` m_objectivec2, { support interfacing with Objective-C (2.0) }`\ | |
| 28 | + | ` m_nested_procvars, { support nested procedural variables }`\ | |
| 29 | + | ` m_non_local_goto, { support non local gotos (like iso pascal) }`\ | |
| 30 | + | ` m_advanced_records, { advanced record syntax with visibility sections, methods and properties }`\ | |
| 31 | + | ` m_isolike_unary_minus, { unary minus like in iso pascal: same precedence level as binary minus/plus }`\ | |
| 32 | + | ` m_systemcodepage, { use system codepage as compiler codepage by default, emit ansistrings with system codepage }`\ | |
| 33 | + | ` m_final_fields, { allows declaring fields as "final", which means they must be initialised`\ | |
| 34 | + | ` in the (class) constructor and are constant from then on (same as final`\ | |
| 35 | + | ` fields in Java) }`\ | |
| 36 | + | ` m_default_unicodestring, { makes the default string type in $h+ mode unicodestring rather than`\ | |
| 37 | + | ` ansistring; similarly, char becomes unicodechar rather than ansichar }`\ | |
| 38 | + | ` m_type_helpers, { allows the declaration of "type helper" for all supported types`\ | |
| 39 | + | ` (primitive types, records, classes, interfaces) }`\ | |

| 42 | + | ` m_isolike_program_para, { program parameters as it required by an ISO compatible compiler }`\ | |
| 43 | + | ` m_isolike_mod, { mod operation as it is required by an iso compatible compiler }`\ | |
| 44 | + | ` m_array_operators, { use Delphi compatible array operators instead of custom ones ("+") }`\ | |
